A durable cover with a soft surface device ( 100 ) includes a substrate ( 10 ), an intermediate layer ( 20 ), an ink coating ( 30 ), and a top coating ( 40 ). The intermediate layer is made of a polyurethane paint. The ink coating contains a polyurethane component. The top coating is made of a polyurethane adhesive. The intermediate layer is applied onto the substrate, the ink coating is formed on the surface of the intermediate layer, and the top layer is formed on the surface of the ink coating and the intermediate layer. The presence of polyurethane in the intermediate layer, the ink coating, and the top coating promotes partial cross-linking therebetween and, thus, helps improve the durability of the cover. Further, the polyurethane contributes positively to the overall softness and flexibility of the cover.
